Steady-state oxygen evolution of WT, Δslr0320 and PpetJ::slr0320 strains grown under NL and HL in the presence of NaHCO3 and DCBQ.
| Strains and Growth Conditions | Oxygen Evolution (μmol O2 mg−1 Chlorophyll h−1) |
|
|---|---|---|
| H2O to CO2 (NaHCO3) |
H2O to Quinone (DCBQ) |

| Normal light | ||
| WT | 311 ± 8 | 467 ± 16 |
| Δslr0320 | 358 ± 12 | 512 ± 13 |
| PpetJ::slr0320 | 330 ± 13 | 478 ± 17 |
| High light | ||
| WT | 435 ± 14a | 538 ± 12 |
| Δslr0320 | 335 ± 16 | 607 ± 15 |
| PpetJ::slr0320 | 444 ± 10b | 508 ± 9 |
Student’s t test was applied. The superscript “a” marks significant differences for WT grown under HL vs. grown under NL in the presence of NaHCO3; the superscript “b” marks significant differences for the complementary PpetJ::slr0320 grown under HL vs. grown under NL in the presence of NaHCO3, both with a significance level of p < 0.05 The results are shown as the means from three independent experiments ± SD.
